KDP crystals were grown from the aqueous solution by the traditional temperature-lowering method and a °point seed ± rapid method. Scatter particles are an important parameter to evaluate the properties of KDP crystals. Light scatter was detected with an ultramicroscopic method. The effects of SO42- , NO3- and Cl- ions on light scatter in the crystals were studied. Results show that SO42- ions have a little effect on the light scatter of KDP crystals and the scatter particles are in a low density. With the increase of the dopant concentration, the density of scatter particles increases a little. For KDP crystals grown by the traditional temperature-lowering method, the existence of NO3- and Cl- ions aggravates the light scatter in KDP crystals severely. The effect on the light scatter of KDP crystals grown by °point seed ± rapid method is not evident. %K additive %K KDP crystal %K ultramicroscopic method %K light scatter %U http://www.jim.org.cn/fileup/PDF/20070216.pdf
